53°42′14″N 0°35′35″E / 53.704°N 0.593°E / 53.704; 0.593The Easington Catchment Area (known as ECA) is a group of natural gas producing fields in the Southern North Sea.
They lie in UK Blocks 42 and 47 between 25 and 30 miles (40 and 48 km) east of the Yorkshire and Lincolnshire coast.
The Mercury field was developed with a subsea installation with well fluids produced to the Neptune NUI via a 10-inch diameter pipeline.
From the Neptune platform co-mingled fluids are transported to a dedicated riser tower on the Cleeton installation via a 16-inch diameter pipeline.
Produced fluids from all three fields are co-mingled on the Minerva platform, and the combined flow exported via a 16-inch diameter pipeline to the BG-operated ECA riser tower bridge-linked to the Cleeton complex.
The Wollaston and Whittle fields are developed via subsea wells and flowlines tied back via a manifold and a 12-inch diameter pipeline to the ECA riser tower, where they are co-mingled with the Minerva hub fluids.
